FINGER-RING.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed April 11, 1917. Serial No. 161,186.

To all whom it may concern:

Be it known that I, AUGUST SCHMIDT, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Finger-Rings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 4

My invention relates to that class of finger rings which are capable of being expanded to enlarge their circumference so as to permit them being readily passed over the knuckles of the finger and then contracted so as to fit securely upon the finger.

As illustrated in the accompanying drawing, Figure 1 is a side elevation showing the ring in its closed position. Fig. 2 shows it opened and Fig. 3 is a detail perspective.

I have shown the ring comprising two parts 2 and 2. These are hinged together as at 3 and the locking means, indicated generally at 4, is shown substantially opposite the hinge. The part 2 of the band of the ring carries a jewel setting 5. It will thus be seen that the hinge and coupling are substantially at the sides of the ring as the jewel setting may obviously be regarded as the top. This is of advantage because it enables the wearer to readily expand the ring by grasping the setting and exerting a slight upward pressure upon it, the finger on which the ring is worn furnishing the necessary resistance by pressure against the part 2 of the band. This function, readily eflected when necessary, is one that is not likely to occur through accident.

As illustrated the coupling may consist of the following formation of parts: The part 2 of the band has an extremity which is reduced in thickness as at 6 and at its outer end carries a pin 7, and at either side of this pin are stops 8. The part 2 of the band is reduced in thickness as at 9 and this reduced portion is slotted as at 10 to receive the pin 7 At the inner end of the slot and at either side thereof are transverse grooves 12 adapted to receive the stops 8 when the parts are closed.

a From the foregoing it will be seen that in order to unlock the parts to expand the ring it is only necessary to pull their meeting ends apart which is readily done by grasping the setting 5 when the ring is on the finger, the finger of the wearer offering the necessary resistance. This causes stops 8 to slide out of grooves 12 and over extremity 9 while pin 7 moves in slot 10. This expanding operation is started, hoiwever, against the spring tension of the ring. The co-acting locking extremities being substantially diametrically opposite the hinge, and

the extremity of part 2 having to move outward, under some slight strain, over the extremity 9, the two parts 2 2 tend to their closed or locked position. If, in the expanding action, and before the parts are fully expanded, the force separating the ends be relaxed, the parts will snap closed. When, however, the parts are fully expanded and the pin 7 has reached the outer end of slot 10 then the parts will, of themselves, remain expanded as the spring tension has been overcome, that is, the extremity of part 2 has passed sufliciently far over extremity 9. Thus it will be seen that the construction in such that the ring parts will remain fully closed and locked, or fully expanded, but not in an intermediate position.

It will be noted that there are no independently movable latches and no parts projecting from the surface of the ring and that the couplin is virtually invisible as the combined thic messes of the two meeting extremities are substantially equal to the thickness of the adjacent parts of the band.

I claim as my invention:

1. As an article of manufacture, a finger ring comprising an expansible split ring one end having a reduced slotted extremity and transverse grooves at the inner end of the slot at the sides thereof, the other end having a pinmovable in said slot and stops stops 8, the other extremity having a slot at either side of said .pin adapted to be en- 10 to receive the pin, and grooves 12 in 10 gaged by and seated in said grooves. which the stops are seated when the ring 2; As an article. of manufacture, an eX- is closed. pansible finger ring consisting of tWo parts In testimony whereof, I have signed this having reduced overlapping extremities one specification. of which slides on the outer faced the other extremity and is formedwith a'pin 7 and AUGUST SCHMIDT.
